LIQUm-MEASURING VESSEL.

SPECIFICATION forming part Of Letters Patent N0. 450,383, dated April.14, 1891.

Application filed August 25, 1890. Serial No. 363,021- (No model.)

To all whom, t may concern.-

Beit known that I, DAVID E. WOLFF, a citizen of the United States,residing at Hagerstown, 1n the county of Washington and State ofMaryland, have invented certain new and useful Improvements in GraduatedMeasuring Devices; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention consists in a new and improved combined pumping, lling, andmeasuring apparatus, which will be hereinafter fully described andclaimed.

Referring to the accompanying drawings, Figure 1 is a side view, partlyin section, of the complete apparatus. Fig. 2 is afront View of theupper part of the apparatus. Fig. 3 is a detail view on an enlargedscale, hereinafter referred to. Fig. .5a is a sectional view taken online a d of Fig. 3. Fig. 4is a similar view of a slightly-varied form,hereinafter described.-

The same numerals of reference indicate correspondingl parts in all thefigures.

Referring to the several parts by their designating numerals, 1indicates an upright supporting-frame, which is secured upon theplatform or iiooring 2. Upon a bracket 3 at the upper end of thissupporting-frame is mounted -a reservoir 4. The reservoir is providedwith the usual gage 4t.

To the rear of the frame 1 is arranged a pump 5, the spout of which isconnected by a pipe 6 with the upper part of. the elevated reservoir. Tothe lower part of the pump is secured the upper end of a tube 7, thelower end of which communicates with the lower reservoir or source ofsupply, usually a barrel, as 8, arranged belowthe platform 2. The bottomof the reservoir 4 communicates through a neck 9 with the top of avertical.

measuring-cup 10, the passage of liquid from the elevated reservoir tothe cup being controlled by a valve 11 in the neck 9. The inclinedbottomof the cup 10 in like manner communicates with the top of a smallermeasuringcup 12,beneath which is arranged a smaller cup 13, and beneaththat a still smaller cup 14. A valve 11 is arranged at the bottom ofeach vertical measuring-cup in the neck 9 at the lower end thereof, andthe end of each valve-stem 11L is extended and has secured upon it aneccentric-disk 11b. A separate air vent or tube 15 leads from each neck9below the valve arranged in said neck and extends out and then up untilits open upper end is on a level With the upper end of the elevatedreservoir 4. Each air-tube 15 is provided with a valve 16, and the upperend of this valveshaft has a ring 17 secured to it, in which theeccentric-disk 11b on the extended end of the valvefstem 11L tits andturns. These valves 11 and 16 are so arranged with relation to eachother that when the valve 11 is turned shut the valve 16 in the air-tube15 will, through the connecting-link 17, be opened.

When it is desired to measure off the quant-ity of liquid which thesmallest and lowermost measure 14 will contain, the valve at the bottomoi' this cup is closed and the valves in the necks of the othermeasuring-cups are opened, allowing the liquor to run down from theelevated reservoir into the lower measure. When this measure is full,the valve 11 above it is closed and the valve at the bottom of the cup14 opened. As the valve 11 at the top of the cup 14 is turned to closeit, thus shutting off the ilow of further liquor into this cup, thevalve 16 in the lower air-tube 15 is opened through the connecting-link17, thus opening the air-vent and allowing the air to enter into thelower measure 14 as the liquid runs out of the same.

In Fig. 4 I have shown waA slightly-varied form of valve construction inwhich the top of each measuring-cup is provided with a short air tube orvent 18, and the end of the valverod 11n is extended, passes throughthis short tube, and has a valve 16 mounted on it within the air-tube,the two valves 11 and 16 being so arranged with reference to each otherthat when one is closed the otherpis opened, and vice versa.

- To the top of the reservoir is connected the upper end of an air andoverflow pipe 19, the lower end of which communicates with the lowerreservoir 8. By this arrangement this pipe acts as an air-vent while theliquid is being pumped into the reservoir, and if too much liquid ispumped up into the reservoir IOO it will run over through this pipe andbe conducted by it back into the lower reservoir, as will be readilyseen.

2O indicates an adjustable bracket sliding vertically on the recessedlower part of the supporting-frame l. This bracket is raised and loweredthrough a lever 21 and connecting-link 22, and upon its upper face,around which an annular iiange 23 is secured, is seated the vessel 24,into which the liquid is to be measured. This bracket is provided with aflexible drip-tube 25, which runs down and connects with the pipe 19, sothat if the vessel 24is overrun or any drippings fall from the lowermeasuring-cup they will run down through this tube back into the lowerreservoir S-and will thus be saved.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, operation, and advantages of myinvention will be clearly understood.

It will be seen that my new and improved combined apparatus iscomparatively simple in construction and very eflicient in its operationand will effectually prevent all leakage and waste whatever.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

of valves operating simultaneously, one clos-V ing when the other opens,substantially as and for the purpose set forth.

2. In a liquid elevating and measuring apparatus, the combination of apump connected with the source of supply or lower reservoir and with theplace of delivery or upper reservoir by pipes, the upper reservoir forreceiving the elevated liquid', a series of meas-V uring-cups connectedwith the bottom of the upper reservoir, each provided with a vent andvalves, as described, and an overflow and waste-preventing apparatushaving pipe-connection with the lower and upper reservoirs,substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

DAVID E. WOLFF.
